UNION FABRIC.

Specification of Letters Patent.

Patented Dec. 2?. z n f ,i

Application filed August 4, 1914. Serial No. Sl.

To all whom it may concern.:

Be it known that-I, DnLnnn'r W. NOR- 'rI-mor', citizen of the UnitedStates, residin at Brookline, in the county of Norfolk anv State ofMassachusetts, have invented new and useful Improvements in UnionFabrics, of which the following is a specification.

My invention relates to textile fabrics, and its objects are to producea union cloth of new texture, to preserve the durability of the clothwhile at the same time increasing the attractiveness of its appearance,and to utilizel by a combination of materials a new result notheretofore obtained by each.

My invention primarily consists in interweaving woolen or worsted yarnswith cotton yarns together with additional threads of fiber silk to ivea spotted and brilliant effect to the goos and to reinforce the clothand preis'erve its durability, these materials being united so as topresent on the face of the goods a woolen or worsted backlgrounddisplaying at'regnlar intervai'sspots Xof fiber silk, andron the'back ofthe'goods' a surface largely of cotton. My invention further consists inthe improvements and novel arrangements of maist . time to displayandpreserve an ornamentalV terial l'xereinafter'more particularly'described and claimed.

It has been common vin the manufacture ofA shoes for many, years toemploy in the constructioncof the upper as a substitute for leather,textile fabrics of various kinds. In view of the rough usage to which itis likely to be exposed the cloth employed for this purpose must bedurable and have goed wearing qualities.V The cloth should also at alltimes present an attractive appearance. Toproduee a'fabric whichAis ableto withstand exposure to the weather,vnnd the wear and tear to which ashoe upper must necessarily be subject, and at the same aspect has beenheretofore a question of much study. and in` general of unsatisfactorysolution. 'ilhere the ornamental apearance of the V-cloth nhas beenattained, it lias been at vthe 4sacrifice of the wearing qualities ofthe upperfgn'and where the cloth has been of thefduraljle characterdesired the decorative quality has been dispensed.

with. So far as I know, I am the first person to utilize for the clothof a shoe upper, a combinatioi'x of woolen or worsted andaettcn yarnsand yarns of ber silk in s uch-` proportions and in such arrange ment asfully to accomplish the obiect of my Invention.

Attention is hereby directed to the drawl -cross section on line 3-3 ofFig. i.;

Referring to the drawing, the fabric 'i is constructed of war yarns 5land the weft yarns 6 and 7. he warp yarns 5 are preferably of Vwoolenor worsted material and in the com letcd fabric substantially cover thespaces etween the spots and form the background on'the face of the goods'and furnish a wearing and protective sur-A face. The weftr yarns 6 arevegetable in or1gin,"preferably cotton or linen and are woven as shownto form a fillig and in' large part a backing for the clon, and tofurnis tensile strength `and.resiliency to the fabric. The weft yarns 7are @ber silk;

these yarns are laid as shown to produce.

a spotted appearance nponthe face of' the goods, and serve not only toornament the cloth but also to add greatly to its durability andutility.

By the combination :of material above-set appearance without in ytheslightest degree e iminating the Wearing qualities essential to thedurability of my lmprovecl cloth when 'used for shoe uppers, for whichthe fabric is particularly designed. Preferably I use substantially anequivalent quantity by Weight of each of the War and weft` yarns, thelatter being suppliv in the proportion of ap roximately one half libersilk and one lha f of the other material used for thev filling'` Y WhileI have described and shown Aa par.- ticular arrangementof warp and weftyarns, I by no means desireso to limit my invention. Any arrangement ofthe. yarns,

whether' as warp or Woof' yarns., forming a woven fabric in which woolis used to construct the face thereof with additional warp or woot yarnsof fiber silk give a spotted effect, and in which-cotton or similarmaterial is used to aid. in forming the forth, Iicoihbine in onefnbric adecorative ing and back, is wa'xnh pirit and 'Scope-1f my nvenoa. l
